Well before Naomi Osaka was a multiple-time Grand Slam champion, she was often known as the tennis player with an intense video-game hobby. 

"On practice days, Osaka is on the court for four hours," Kevin Nguyen reported for GQ. "Then she goes home and plays four, sometimes five hours of video games."

Now, as not just a star athlete but also a cultural icon, Osaka has become one of the faces of the PlayStation 5. In a video promoting the console, she talked about how gaming assists her in managing an often-overwhelming life on tour. 

"It really helps me out 'cause I'm stressed out most of the time during the day while I'm at tournaments, but then I come home and I can play the PlayStation and chill out," Osaka said. "You feel so immersed that you're not even thinking about what's happening in real life."

With three major titles at age 23, she seems to be striking a balance that gives her the best of both worlds, real and virtual.
